Singlet-doublet dark matter beyond freeze-out
Prudhvi N. Bhattiprolu, Aaron Pierce, Alexander Takla
The Singlet-Doublet fermion model of dark matter is an economical weak-scale dark matter model that realizes the dark matter abundance through interactions with the electroweak bos…
Singlet-doublet dark matter revisited
Prudhvi N. Bhattiprolu, Evan Petrosky, Aaron Pierce
The singlet-doublet model is an economical model of weakly interacting dark matter. We revisit it in light of improved dark matter direct detection limits. We characterize the now…
Sub-MeV Dark Sink Dark Matter
Prudhvi N. Bhattiprolu, Robert McGehee, Evan Petrosky +1
A Dark Sink uses dark-sector interactions to siphon energy from dark matter to lighter dark degrees of freedom, i.e. dark radiation. Here, we extend dark matter models containing a…
Lepto-axiogenesis with light right-handed neutrinos
Patrick Barnes, Raymond T. Co, Keisuke Harigaya +1
We study lepto-axiogenesis in theories where the right-handed neutrino is light enough that its dynamics affect the determination of the baryon asymmetry. When compared with theori…
A Dark Sink Enhances the Direct Detection of Freeze-in Dark Matter
Prudhvi N. Bhattiprolu, Robert McGehee, Aaron Pierce
We describe a simple dark sector structure which, if present, has implications for the direct detection of dark matter (DM): the Dark Sink. A Dark Sink transports energy density fr…
